Some shiny new features for the parallel programming crowd. http://www.bit-tech.net/news/bits/2012/10/16/nvidia-cuda-5/1
Damn, Nsight is for eclipse xD .... without me. I hate this IDE ^_^. About folding, it will depends on developpers. Is this API compatible with older gen cuda capable GPUs ? I think I'll keep passing my way. Don't like closed system and hardware restricted code. OpenCL has my choice.
i think they'll have to work hard to keep ahead, especially now that Microsoft have their own implementation via C++amp that can target any GPU.
GPU mining is starting to reach it's limits. You'd be better of investing in an ASIC based miner, such as those made by butterfly labs. $150 will get you a plug in board that will do 4.5GH/s. And within a power envelope much much smaller than if you used GPUs to get that level of performance.
